此脚本使用泄露的 HDCP 主密钥（位于 master-key.txt 中）在 Python 中实现了 HDCP 密钥生成算法的简化版本。
Usage: generate_key.py [options]
Options:
-h, --help show this help message and exit
-m FILE, --master=FILE
load master key from FILE
-k, --sink generate a sink key rather than a source key
--ksv=KSV use a specific KSV expressed in hexadecimal
-j, --json output key and KSV as JSON
-t, --test generate source and sink keys and test they work
示例:
# Generate a sink key with KSV 0x54f0af39a8 and output the result in JSON
./generate_key.py -k --ksv 54f0af39a8 -j
# Generate a source key with a random KSV and output the result in a
# human-readable form
./generate_key.py
# Run a self-test to make sure the source a sink key generation is consistent
./generate_key.py -t
